Paris Saint-Germain have confirmed that Thiago Silva fractured a bone in his cheek in Friday's 1-0 win over Lorient.
The Brazil international was forced off during the first half of the game at the Stade du Moustoir after taking a blow to his face while jumping to head the ball.
It was initially feared that the centre-half could be facing a lengthy spell on the sidelines, thus putting his participation in PSG's Champions League quarter-final tie with Chelsea in doubt.
However, the Ligue 1 leaders confirmed on Saturday that the injury did not warrant an operation.
"Examinations on Thiago Silva performed so far have revealed a fractured of the left zygomatic bone," read a club statement.
"His condition did not require surgery. Downtime will depend on the evolution of pain in the coming days.
"His participation in the quarter-finals of the Champions League should not be compromised."
PSG host Chelsea at the Parc des Princes on April 2 before travelling to Stamford Bridge for the second leg six days later.
